Chittagonian or Chittainga, also Satgaya (চাঁটগাঁইয়া) is an Indo-Aryan language spoken by the people of Chittagong in Bangladesh, and in much of the southeast of the country. It is closely related to Bengali and is often considered to be a nonstandard dialect of Bengali, but the two are not mutually intelligible.[4] It is estimated (2009) that Chittagonian has 13–16 million speakers, principally in Bangladesh.[5]
